PHP and Laravel: Building Modern Web Applications

14 min read
PHP has evolved dramatically from its origins as a templating language. Modern PHP with Laravel has transformed into a sophisticated, developer-friendly ecosystem. Laravel provides elegant syntax, powerful abstractions (Eloquent ORM, middleware, service containers), and a thriving community. This guide explores Laravel's capabilities, when to use it, and how it compares to other backend stacks.

Modern PHP: Beyond the Legacy

PHP 8+ brought significant language improvements: typed properties, named arguments, attributes, match expressions, and nullsafe operators. Combined with Laravel's framework features, modern PHP is a highly productive language for web development. PHP remains unmatched for shared hosting deployments and has deep integration with web infrastructure (Apache, Nginx). A single PHP file can serve a request without compilation — development velocity is exceptional.

app/Controllers/ProductController.php
namespace App\Controllers;

use App\Models\Product;

class ProductController {
    public function index() {
        $products = Product::all();
        return view('products.index', compact('products'));
    }

    public function show(Product $product) {
        return view('products.show', compact('product'));
    }
}
info

Laravel's routing, dependency injection, and service container provide patterns familiar to developers from Node.js, Python, and Java ecosystems.

Eloquent: An Elegant ORM

Laravel's Eloquent ORM is one of the most intuitive database abstraction layers available. It combines expressiveness with safety through query builders and relationship management. Eloquent automatically handles common patterns like eager loading to prevent N+1 queries, relationship constraints, and model callbacks.

app/Models/Product.php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Product extends Model {
    protected \$fillable = ['name', 'price', 'category_id'];

    public function category() {
        return \$this->belongsTo(Category::class);
    }

    public function reviews() {
        return \$this->hasMany(Review::class);
    }

    public function scopeActive(\$query) {
        return \$query->where('active', true);
    }
}
tip

Eloquent's query scopes and lazy eager loading patterns prevent N+1 problems while keeping your code readable and maintainable.

Laravel's Feature-Rich Ecosystem

Laravel includes authentication (with scaffolding), authorization (policies), validation, middleware, task scheduling, queues, cache, sessions, and file storage out of the box. Laravel Mix (or Vite integration) handles frontend asset compilation. Artisan, the command-line tool, generates boilerplate and runs migrations. This comprehensive toolkit means fewer decisions and faster development compared to Flask-like frameworks.

  • Built-in authentication with preset UI scaffolds (Breeze, Jetstream)
  • Authorization policies for fine-grained access control
  • Eloquent relationships: one-to-one, one-to-many, many-to-many, polymorphic
  • Job queues for background processing (Redis, SQS, RabbitMQ)
  • Task scheduling for cron-like operations without cron

Scaling Laravel Applications

Laravel scales through horizontal deployment: stateless applications running behind load balancers. Laravel Horizon monitors job queues, while Laravel Telescope provides debugging and profiling. For real-time features, Laravel Reverb provides WebSocket support. Database optimization, caching layers (Redis), and CDN distribution follow standard web architecture patterns. Laravel's shared hosting origins mean it's designed for simple deployment — no container orchestration required.

note

Laravel's Session and Cache systems are pluggable — use Redis for both to ensure consistency across multiple server instances.

Laravel vs Other Backend Frameworks

Compared to Django, Laravel offers similar batteries-included philosophy with different syntax and ecosystem. Compared to FastAPI, Laravel's routing and ORM are more opinionated but require no async complexity. Laravel excels for server-rendered applications with traditional databases and simple deployment requirements. FastAPI wins for high-concurrency microservices. Django wins for data-heavy applications with complex admin interfaces.

  • Choose Laravel for rapid development and shared hosting deployment
  • Use it when your team values developer experience and ecosystem maturity
  • Consider alternatives if you need extreme performance for high-concurrency APIs
  • Laravel's strength is full-stack web applications, not headless APIs

Building Modern Applications with Laravel

Modern Laravel applications pair the framework with frontend tools: Inertia.js for reactive server-rendered interfaces combining Laravel backends with Vue/React frontends, or build a separate SPA with your API. Livewire provides real-time interactivity without JavaScript. Docker containerization is standard for local development and deployment. Laravel Sail provides a Docker development environment requiring only Docker and PHP.
